if `triangleDEF` `~=` `triangleBCA` write the parts of BCA that correspond to : `lfloorEF`

if triangleDEF ~= triangleBCA write the parts of BCA that correspond to : lfloorF

if triangleDEF ~= triangleBCA write the parts of BCA that correspond to : lfloorE harr lfloorC

If triangleABC ~= triangleFED under the correspondence ABC harr FED, write all the corresponding congruent parts of the triangle.

If triangleABC and trianglePQR are to be congruent, name one additional pair of corresponding parts. What criterion did you use:

What is a flower ? Write the essential parts of a flower.

In the given diagram, write the names of parts shown with lines.

a] Draw a diagram of the longitudinal section of a flower and label on it sepal, petal, ovary and stigma. OR Draw the diagram showing the longitudinal section of a flower. Label the following parts : i] Style ii] Anther. b] Write the names of male and female reproductive parts of a flower.

(a) Identify A, B, and D in the given diagram and write their names. (b) What is pollination? Explain its significance. (c) Explain the process of fertilization in flowers. Name the parts of the flower that develop after fertilization into (i) seed, (ii) fruit.

Examine structures a through j, shown below, with respect to their symmetry or lack of it. Assume that the five-membered rings and the ring in compound g are planar. The wedge-hatched bonds in b, c, d & e designate specific configurations. Also, for the acyclic compounds assume stable anti conformations. Answer each of the following questions by writing letters (a through j), corresponding to your selections, in each answer box. If there is no structure that fits the description enter an x in the answer box. Which structures are chiral ?
